What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: This study aims to comprehensively explore the bidirectional association between obstructive sleep apnea (OSA) and diabetic kidney disease (DKD) through a systematic review and meta-analysis. Method: Systematically search for relevant literature on the association between OSA and DKD published from database inception to September 2025. Searches were performed in the Cochrane Library, PubMed, Embase, and Web of Science. Study quality was assessed with the Newcastle-Ottawa Scale (NOS). Meta-analysis, sensitivity analysis, and publication bias assessment were conducted using Review Manager 5.4, while R software was employed to calculate prediction intervals. The certainty of evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) framework. Result: A total of 14 articles involving 5,316 subjects were included. Patients with OSA exhibited a 1.92-fold increased risk of DKD compared with the control group (OR = 1.92, 95% CI: 1.59, 2.32, P < 0.0001). Subgroup analysis by OSA severity indicated a higher risk of DKD in patients with severe OSA (OR = 2.29) than in those with mild to moderate disease (OR = 1.52). Additionally, OSA patients showed significantly lower estimated Glomerular Filtration Rate (eGFR) levels (MD = -8.61, 95% CI: -12.92, -4.30) relative to non-OSA controls. In the reverse analysis, while the prevalence of OSA did not differ significantly between DKD and non-DKD groups (OR = 1.56, 95% CI: 0.71 - 3.43, P = 0.27), patients with DKD had significantly higher apnea-hypopnea index (AHI) (MD = 6.48, 95% CI: 1.74 - 11.22, P = 0.007) and lower average blood oxygen saturation (M-SaO2) (MD = -0.59, 95% CI: -0.82 to -0.36, P < 0.00001). No significant differences were observed in the lowest blood oxygen saturation (L-SaO Conclusion: A significant bidirectional association exists between OSA and DKD, suggesting a mutual exacerbation of risks between the two conditions. These findings highlight the clinical importance of enhanced OSA screening in diabetic populations and regular renal function monitoring in OSA patients.
